| DISCOVERY SYSTEM |
|
The Discovery system uses the new Sony 3.5'' diskette to save in full safety the programs and data of the Spectrum or Spectrum+. The diskette has a capacity of 180 KB and a second drive can be installed. The commands of the operating system are similar to those of Sinclair Microdrives. The case includes a power supply and various Spectrum expansion connectors. In short, a lot of hardware qualities, but an incomprehensible defect: the data transfer speed is slower than Microdrives, whereas a disk drive is able to be ten times faster than a tape reader. Discovery did not meet success, certainly for this reason, but also because of its high price, not compatible with the Spectrum's young users' purse. |

**(8)** This empty socket receives a 2 Kb. RAM chip when a second disc drive is installed.\
**(9)** 6821 Circuit, in charge of disc drive control.\
**(10)** Each disc drive uses an internal RAM area to avoid using Spectrum RAM.\

| KEMPSTON JOYSTICK INTERFACE |
|
Peter says:\
I'm not sure if this was the first joystick interface for the Spectrum but it defined a standard that was never displaced. Most games carried the words 'Kempston joystick compatible' Says it all really! They later revised the interface to offer 2 joystick connectors

| CHEETAH SPECDRUM |
|
About the Specdrum, Peter says:\
This was the most fun add-on I ever bought for the Spectrum. You had to connect it to a phono input on a stereo amp, load up the software and away you went. You could enter the rhythm in real time or step time and it had 8 sounds it could play at once. The sound was perfect and still sounds good today. They released some extra drum kit sounds to expand the Specdrum's sound library, Afro Kit and Electro Kit are the ones I remember and purchased. I don’t think any Spectrum should be without this Add-on, it rocks!!
Price: About £30 around 85-86

| ALPHACOM 32 |
|
Alphacom 32 is the well-known and the cheaper printer for the Spectrum, offering exactly the same features as the ZX Printer : full Spectrum characters set, 32 char. / line and silver plated thermal paper. Alphacom 32 uses its own power supply. june 84 price : 181 -E- (France). |

| FLOYD 40 |
|
Floyd 40, from the manufacturer Shiva Marketing, doesn't seem to be very reliable with its very thin plastic case and its wooden paper axis ! However Floyd features are better than Alphacom ones: use of white thermal paper more readable and less expensive, only one cable to connect it to the Spectrum (power and data) and better printing quality. Moreover, Floyd 40 has larger characters set and printing options : double height and width, text printing in the four directions and more advanced and accurate graphic abilities (5 x 7 dots head). On the other hand, the printing is rather slow and the print width doesn't exceed 8 cm. |

| ZX-81 THERMAL PRINTER |
|
This is a small thermal printer (of very poor quality !). It can print all the graphical characters of the Spectrum and can print 9 lines of text per inch. It was possible to make a hard copy of the screen thanks to the "Copy" command.
This tiny thermal printer can also be used with the ZX-Spectrum. |

| INSIDE A MICRODRIVE CARTRIDGE |
|
The support used in the cartridge is a videotape of 2 mm in width, and 8 meters in length. The video support was chosen for its biggest mechanical resistance. In running mode, the full tape length is covered in about 7 seconds and the information is transferred at 6 Kb. per second (1.5 Kb./sec. for a standard cassette). The recording is made simultaneously on two parallel tracks with a density of 200 bytes per centimeter. The information is organized in sectors of 512 bytes. Any program can be stored or loaded in 15 sec. Maximum. Each cartridge can store up to 100 Kb, but only 85 - 90 are available for the user. |
